ISO 639 code: DEU
The modern German alphabet consists of the twenty-six letters of the ISO basic Latin alphabet. German uses three letter-diacritic combinations (Ä/ä, Ö/ö, Ü/ü) using the umlaut and one ligature (ẞ, ß (called Eszett (sz) or scharfes S, sharp s)) which are officially considered distinct letters of the alphabet.
The Capital ẞ was declared an official letter of the German alphabet on 29 June 2017.
In the past, long s (ſ) was used as well, as in English and many other European languages.
The eszett or scharfes S (ẞ, ß) represents the unvoiced s sound. The German spelling reform of 1996 somewhat reduced usage of this letter in Germany and Austria. It is not used in Switzerland and Liechtenstein.
As the ß derives from a ligature of lower-case letters, it is exclusively used in the middle or the end of a word. The proper transcription when it cannot be used, is ss (sz and SZ in earlier times). This transcription can give rise to ambiguities, albeit rarely; one such case is in Maßen (in moderation) vs. in Massen (en masse). For all caps usage, an uppercase ß was added to the German alphabet on 29 June 2017; however, the former version SS is still allowed as an alternative. In 2008, it was included in Unicode 5.1 as U+1E9E, and since 2010 its use is mandatory in official documentation when writing geographical names in all-caps.
Although nowadays substituted correctly only by ss, the letter actually originates from two distinct ligatures (depending on word and spelling rules): long s with round s (“ſs”) and long s with (round) z (“ſz”/”ſʒ”). Some people therefore prefer to substitute “ß” by “sz”, as it can avoid possible ambiguities (as in the above “Maßen” vs “Massen” example).
Incorrect use of the ß letter is a common type of spelling error even among native German writers. The spelling reform of 1996 changed the rules concerning ß and ss (no forced replacement of ss to ß at word’s end).
Wachstube and Wachſtube are distinguished in blackletter typesetting, though no longer in contemporary font styles.
In the Fraktur typeface and similar scripts, a long s (ſ) was used except in syllable endings (cf. Greek sigma) and sometimes it was historically used in antiqua fonts as well; but it went out of general use in the early 1940s along with the Fraktur typeface. An example where this convention would avoid ambiguity is Wachstube, which was written either Wachſtube = Wach-Stube (IPA: [ˈvax.ʃtuːbə], guardhouse) or Wachstube = Wachs-Tube (IPA: [ˈvaks.tuːbə], tube of wax).
Although the diacritic letters represent distinct sounds in German phonology, they are almost universally not considered to be part of the alphabet. The diacritic letters ä, ö and ü are used to indicate the presence of umlauts (frontalizations of back vowels). In proper names and ethnonyms, there may also appear a rare ë and ï, which are not letters with an umlaut, but a diaeresis. To separate the au diphthong, as well as some others, which are graphically composed of potentially umlaut-holding letters, the acute accent is sometimes used (e.g. Saúdi-Arabien).
